I have a 2018 Tahoe with 93K miles and the TPMS sensor activated. The sensor will deactivate intermittently but will go on again for an unknown reason. I had all 4 sensors changed and re-flashed 4 times over the last 2 months in an attempt to cure the problem. I have since taken it to 2 different Chevrolet dealerships as one re-flashed the sensors AGAIN and with 10m minutes of driving, the light came back on. The dealership wanted to charge me ANOTHER diagnostic fee and I refused. I went to another Chevrolet dealership and they re-flashed the body module, checked the module antenna connections and replaced the battery in my FOB. I picked up the Tahoe and the light came on again after driving 18 miles. When the light comes on, the front right tire is dashed out on my info screen and I have noticed that the door lock / unlock button on my driver's door has a weak signal when the other 3 doors respond properly. I'm pretty much at my wits end and cannot seem to find a technician that can figure this out.

the TPMS have batteries..mine all went out after ~140K..
check the part numbers of the TPMS..there are several..check rockauto for your specific year.
there is a GM direct parts house in some of the other threads..
as far as the door(s)..the door lock solenoid could be on its way out. but odd since
power door lock actuates all the doors at once.
the FOB..well with the replaced battery its hould be good. unless it has to be programmed.

8 Year old sensors, probably need to replace them all. the rest is in your mind. See you $200 later.....

Welcome to the Forum from NH.
Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.
I hope that you will become a participating member in the Forum's discussions.
Pics of the truck, please. If we can't see it, it does not exist.
You state that you replaced all 4 TPMS sensors. When did you do that, and where did you have them replaced (sensor quality question)?
Has the right front wheel always been the one with the 3 dashes on your info screen, ever since this issue started?
